Hello Matthew,

If you dump the endpoint properties for this device (with the Conexant driver)
do you see a PKEY_AudioEndpoint_Supports_EventDriven_Mode property with value 1?
I don't know, and I'm not sure I'll be able to test again with the PC (it's "flying away"
tomorrow), but as I said, KSPROPERTY_RTAUDIO_QUERY_NOTIFICATION_SUPPORT returns TRUE, which I guess
is the "horses mouth" with regard to the PKEY_AudioEndpoint_Supports_EventDriven_Mode
property (?)
I mean, I'm down in the WDM/KS dumps, so WASAPI Endpoint properties don't really concern me. But it
is a fact that Windows 7 somehow does "make it" to the device buffer, which I don't. The
docs say "Events are registered using KSPROPERTY_RTAUDIO_REGISTER_NOTIFICATION_EVENT _after_
successfully calling KSPROPERTY_RTAUDIO_BUFFER_WITH_NOTIFICATION" and that never happens,
which it acc. to KSPROPERTY_RTAUDIO_QUERY_NOTIFICATION_SUPPORT should (!)

and I get FALSE result and GetLastError() returns ERROR_INVALID_PARAMETER. This
code works fine on _several_ other machines, also on Windows 7 machines, and
the device works fine otherwise in Windows 7, hence I must be doing something
wrong (?)
Further to this, just for the heck of it, I uninstalled the Conexant device,
and during the driver installation procedure, I skipped Windows update so that
the Microsoft HDAudio.sys was chosen instead, and then the code works fine. A
workaround, but not good, since the Conexant driver does work in Windows 7, so
I'd like to be able to make portaudio work with it too...
